چکیده
characteristics at 20°C. The threshold current (density) is 57mA (-3.2kA/cm2), which is as low as that for a 650nmband laser diode with a double-heterostructure (DH structure) [l]. We believe this to be the lowest ever value for a 630nmband AlGaInP laser diode. The maximum CW output power is -15mW, and this is limited by the C O D (catastrophic optical damage) of this structure. The slope efficiency of a laser diode is as high as 0.4 W/A for a 670 nm-band laser diode with a D H structure [8]. The maximum CW operating temperature is 50°C.

Low-noise picosecond soliton transmission by use of concatenated nonlinear amplifying loop mirrors
We compare two systems that are specially configured with loop mirrors to provide stable picosecond soliton transmission. One configuration, created by Smith and Doran [J. Opt. Soc. Am. B 12, 1117 (1995)], uses nonlinear optical loop mirrors. This configuration is compared with another that uses nonlinear amplifying loop mirrors, the configuration of which we systematically determine from the a...

We numerically analyze the effectiveness of a nonlinear optical loop mirror (NOLM) based on standard communication fiber with randomly varying birefringence for demultiplexing streams of picosecond pulses at 100 GHz. A broad switching window of about three pulse full-width at half maximum (FWHM) can be obtained. The device performance is defined by the pulse duration, the dispersion of the fibe...
متن کاملUltra-fast fibre laser systems based on SESAM technology: new horizons and applications
A promising route to manufacturing portable (sub-)picosecond fibre lasers is to use a semiconductor saturable absorber mirror (SESAM). With SESAMs, the mode-locked regime can be achieved for different values of cavity dispersion for a broad spectrum ranging from 0.8 to 1.6μm. The fibre lasers, characterized by a high efficiency and reliability and a small footprint, are very attractive for appl...

Pumping of highly-nonlinear microstructured fibers with zero-dispersion around the pump wavelength of a 50kW peak-power picosecond Yb-fiber laser allowed extensive polychromatic picosecond operation down to 525nm in all-fibre format. Spectral power densities over 1mW/nm and potential of further pulse compression to femtoseconds is demonstrated.
متن کاملPicosecond soliton transmission by use of concatenated gain-distributed nonlinear amplifying fiber loop mirrors.
Stable picosecond soliton transmission is demonstrated numerically by use of concatenated gain-distributed nonlinear amplifying fiber loop mirrors (NALMs). We show that, as compared with previous soliton transmission schemes that use conventional NALMs or nonlinear optical loop mirror and amplifier combinations, the present scheme permits a significant increase of loop-mirror (amplifier) spacin...
